IMPROVEMENT IN STEAM-PUMPSQ- The Sehediile` referred to in these Letters Patent and making if thejsame.

LJOHARLES LQSTEvnns, of Galesburg, in the countybt" Knox and State of1llinois,\have invented' certain Improvementsin lDouble Self-acting Wooden Steam-Puinps,of which `thefollowingis aspeciiica-V tion.. i

' Nature mul Objects of the Invention.

f 'Ihci'rst `part of my invention relates tothe construction ot' the wooden air-tight tanks, as hereinaf tei' fully described.

Thesecond part of my invention relates to the arrangement of devices i'oropening and closing -alteinately the coeksthrongh which steam is admitted to the tanks, as hereinafter' described, Y

The third' part ofniyinvention relatesto the ai'- rangements of the blow-offpipes, and the devices for operating the saine, as hreinafter fully described.

'Iliedbui'th part of my invention relates to th'ecom-- hinationandV arrangement of pipes with the tanks,

the object of which is to pass a jet of cold waterfrom one tank tothe other, and alternately, to aid in-"the `rapid condensation of the steam. i i The fifth partyof my invention relates to the co u;

struction of the diaphragimgwhich :is intervened between thefsurfaiee of the wate`r and the steam in the tanks, mainly for thepiiigpose of preventing vthe water,- when entering thcianks, from being dashed to the top-and coolingthe same, together with the air oo ntained in thctanks. Y

vIi F, and-'extending downward through the tanksA Yi is a pipe connecting the' near ends of the T`on J I A' tothe top of the tank A, and has -a @lack-valve,

The diaphragm L is pierced in the center with a vhole near three times the diameter of the rod G, through which the rod G passes.

The tanks A A are constructcdof' lwooden staves,

from four to ten inches thick, as the tanks may be smaller or larger, and are dressed slightly tapering,

Aso that the tank itself may be a little larger at the base -than at the top.

Holes' are bored longitudinally withand b'etween the staves, as shown at tig. 2, through which the bolts a a a" a" may pass.

'I he tops and bottoms of the tanks may be formed of wood, and rest dat. on the ends of the tanks, as shown at A', fig. 1, or they may be formed ot' metal, ,and have a wooden lining or projection, as shown by the dotted lines at the tank A, fig. 1, which 1ining is made to t in an annular rabbet in the upper end of the tanks.

The heads of the tanks are heldin position by bolts a" a" a a" with heads and and nuts as usual.

rlhe object informin'g these tanks of wood is to present the condensation which occurs in metal tanks when the steam is first admitted, and before its full power has'been used in expelling the water.

The bottom of the tanks may be formed of metal, as the steam is prevented striking them by a few inches of water always left in thetank when discharged.

Experience has shown that metal bolts used in staying tanks, if left exposed to the action of the steam inside ofthe tank, would condense a great portion of the steam, thereby causing' great-loss, and, if placed outside of the tanks, the action of the weather soon corrodes them to uselessness, unless they are made very heavy; for these reasons this construction of tanks is deemed especially useful in pumps of this class.

Operation.

lSteam being admitted through the pipe B, and the cockD being open, its passage is uninterrupted until it reaches the arrester or deflector-plate M, by which the descending column is scattered and'thrown to the top and sides of the tanks A', and prevented from coming -in direct contact with the water by theV diaphragm L, the pressure of the steam carrying down the diaphragm L and float J, and forcing ont the water through the pipes U, Y, and X, the valve y .opening to admit its passage, and the valve 'v closing at the same time.

When the water iu the tank has been nearly discharged, the oat J will be carried, by the rapidity of the current, into the tube U, and, striking the collar vH, will carry the rod G down with it, and with the rod G the crank F, thus turning therod C, closing the .cock D, and opening the cock D into the tank A,

where the Asame operation is repeated.

When the steam is admitted into the tank A', ascending the pipe N, it closes the valve n, and its pressure on. the water in the tank A', at the same time,

forces a portion ofthe water inthev tankA', through the pipe N'and valve n', into the upper p art of the tank4 A, where, striking the deflector m, it will be scattered into spray,v and aid incondensing the steam in tank A.

'the rod .C is again rotated to open the cock D', the

same devices turn the key in stop-cock It, so as to close the passage to tank A, and open the passage from the tank A' for the passage of the steam-from it, the valve t opening outwardly, andpreventing any air from rushingin to the pipe S.

lIn my former patent of January 19, 1869, the blow-ott' pipes were arranged iu the top ot' the tanks, and allowed all air to pass ont as the tank filled with water, and the diaphragm to thump the .top of the tank. The present arrangement of the blow-off pipes S, Aallowsa portion of air to remain above the diaresults.` v

It will be readily seen that when the steam is allowed to blow ott from one of the tanks through the pipe S to the extent that .it will force out the resisting atmospheric pressnre,.the jet or spray from the pipes N will condense the remaining portion and produce a vacuum, which, the water rushing in through pipes W, V, and U, will soon fill, the water, as it rises in the tank, carrying up the oat J, which closes the h ole in diaphragm L, andv both ascend on the surface of the water until arrested by the compressed air in the top of the tank. The warm water resting on top of the diaghragm L, and the warm air in the top of the tanks, prevent the condensation of steam, which occurs when wooden diaphragms or followers are used, which do not ll out closely and adjust themselves to thetapcring tanks,vthe part of the rubber diaphragm L,n this invention, which projects beyond the ringK, allowingthe outer edge orperiphery of the sameto rnb closely the inner surface of the tanks at top and bottom. r1`Jhe same feature prevents thoroughly, the water, when entering the tanks, from being dashed past the outer edges of the diaphragm land cooling the air and top of the tank.

The tanks may be placed on suitable supports at any distance abovethc water to which the atmospheric pressure will raise the same, and the water-outlet pipe X may be extended, as desired, the waterbeing expelled through it with a force and rapidity proportioned to the pressure of the steam.
